DOI: 10.17487/RFC9250
This document describes the use of QUIC to provide transport
confidentiality for DNS. The encryption provided by QUIC has similar
properties to those provided by TLS, while QUIC transport eliminates
the head-of-line blocking issues inherent with TCP and provides more
efficient packet-loss recovery than UDP. DNS over QUIC (DoQ) has
privacy properties similar to DNS over TLS (DoT) specified in RFC
7858, and latency characteristics similar to classic DNS over UDP.
This specification describes the use of DoQ as a general-purpose
transport for DNS and includes the use of DoQ for stub to recursive,
recursive to authoritative, and zone transfer scenarios.
This document is a product of the DNS PRIVate Exchange Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
